Thermochemical conversion of microbial mats: A case study on Cr(VI) removal from freshwater.

In response to increasing anthropogenic pollution and metal accumulation in aquatic environments, bioremediation has gained great importance. Microbial consortia are emerging as a promising solution due to their diverse pollutant metabolizing pathways. This study evaluates the role of biotic and abiotic components in microbial mats for Cr(VI) removal from freshwater.

Paint particle pollution in aquatic environments: Current advances and analytical challenges.

Paints, coatings and varnishes play a crucial role in various industries and daily applications, providing essential material protection and enhancing aesthetic characteristics. However, they sometimes present environmental challenges such as corrosion, wear, and biofouling which lead to economic losses and ecological harm. Paint particles (PPs), including antifouling/anticorrosive paint particles (APPs), originate from marine, industrial, and architectural activities, primarily due to paint leakage, wear, and removal, thus significantly contributing to marine pollution.

Low prevalence of microplastic contamination in the bottom sediments and deep-sea waters of the Bransfield strait, Antarctica.

Despite the remoteness of the Antarctic continent and Southern Ocean, microplastic (MPs) contamination has been evidenced in recent years. However, the deep-sea compartments of the Southern Ocean are yet to be investigated. In the present study, we conducted a baseline MP assessment of the deep-sea waters and bottom sediments of the Bransfield Strait, Antarctica.

Chemical analysis of marine microdebris pollution in macroalgae from the coastal areas of Argentina.

Marine microdebris (MDs, <5 mm) and mesodebris (MesDs, 5-25 mm), consist of various components, including microplastics (MPs), antifouling or anticorrosive paint particles (APPs), and metallic particles (Mmps), among others. The accumulation of these anthropogenic particles in macroalgae could have significant implications within coastal ecosystems because of the role of macroalgae as primary producers and their subsequent transfer within the trophic chain. Therefore, the objectives of this study were to determine the abundance of MDs and MesDs pollution in different species of macroalgae (P.

Influence of the geographic location and house characteristics on the concentration of microplastics in indoor dust.

Microplastics (MPs) are known for their ubiquity, having been detected in virtually any environmental compartment. However, indoor MPs concentrations are poorly studied despite being closely related to human exposure. The present study aims to evaluate the presence of MPs in settled atmospheric dust in 60 houses distributed in 12 districts of the metropolitan city of Lima, Peru, and investigate the influence of their geographical location and house characteristics.
